In 1940, Sasebo Naval Shipyard, former facility of U.S. Naval Base, equipped The Musashi, one of the World’s heaviest and most powerful naval vessels built by the Japanese. After sinking during the Battle of Leyte Gulf in 1944, killing 1,023 crew members, Microsoft co-founder Paul Allen and his team discovered her in the Sibuyan Sea off the Philippines in 2015. Allen’s team spent eight years searching when they uncovered it.
